本地Json 调用

1、新建assets 文件夹（在main目录下）

2、创建test.json 格式的文件

3、获取文件流

public class FileUtils {
    public static String getJson(Context context, String fileName){
        StringBuilder stringBuilder = new StringBuilder();
     
        AssetManager assetManager = context.getAssets();
        
        try {
            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(
                    assetManager.open(fileName),"utf-8"));
            String line;
            while ((line = bufferedReader.readLine()) != null) {
                stringBuilder.append(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return stringBuilder.toString();
    }
}

4、网络请求 OKHttp3

public void sendDataCompress() {
        String path = Config.getDomain();
        String fileName = "test.json";
        String foodJson = FileUtils.getJson(getContext(), fileName);

        OkHttpClient.Builder builder = new OkHttpClient().newBuilder();
        builder.connectTimeout(60, TimeUnit.SECONDS);
        RequestBody body = RequestBody.create(JSON, GzipRequestInterceptor.compress(foodJson));

        Request okRequest = new Request.
                Builder().
                url(path).
                post(body).
                addHeader("Content-Encoding", "gzip").
                build();

        final Call call = builder.build().newCall(okRequest);
        call.enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                deliverMessage(e.getMessage());
            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                String res = response.body().string();
                deliverMessage(res);
            }
        });
}
